Atlanta, Georgia Building Permits
Atlanta building permit guide: learn permit steps, costs, review times, zoning, code rules, flood issues, and plan requirements before you build.
Wind
ASCE 7 basic wind speed: typically 115 mph ultimate design wind speed for Risk Category II buildings in the Atlanta area; exposure category, topography, building height, and risk category can change design pressures.
Snow Load
Ground snow load: minimal, commonly about 5 psf or less in the Atlanta area; roof snow and rain-on-snow design should be confirmed using the adopted code and ASCE 7 maps.
Flood
Atlanta participates in the National Flood Insurance Program, and FEMA Flood Insurance Rate Maps apply. Properties near the Chattahoochee River, South River, Peachtree Creek, Proctor Creek, Nancy Creek, and other drainage corridors may require floodplain review, elevation certificates, compensatory storage, or lowest-floor elevation compliance.
Earthquake
Seismic design category is commonly SDC B for many standard Risk Category II sites, but final classification depends on mapped spectral response, soil site class, occupancy/risk category, and ASCE 7 calculations.
Wildfire
Atlanta has limited formal wildfire-code requirements compared with mountain or western WUI communities, but wooded lots, steep slopes, and urban tree canopy can create localized interface risk. Fire access, address visibility, defensible space, and vegetation management may be considered, especially near parks, stream buffers, and heavily wooded parcels.

Approval Timeline
Simple trade permits may be issued the same day to a few business days if the contractor is licensed and the scope is clear. Residential remodels commonly take 2-4 weeks; additions, new single-family homes, and projects needing zoning, arborist, or historic review often take 4-8+ weeks. Commercial tenant build-outs commonly take 4-8 weeks, and larger commercial, mixed-use, change-of-occupancy, or land-disturbance projects can take 8-12+ weeks depending on review comments and resubmittals.
Common Requirements
Typical submittals include a completed permit application, owner/contractor information, Georgia contractor license where required, project valuation, site plan, construction drawings, floor plans, elevations, structural details, energy code compliance documentation, MEP drawings when applicable, erosion control or stormwater information for exterior work, and tree/arborist documentation when regulated trees are affected. Commercial work usually requires sealed architectural/engineering plans, life-safety plans, accessibility details, occupancy classification, construction type, fire protection information, and special inspection forms when required.
Zoning Information
Atlanta uses its Zoning Ordinance, including residential, commercial, industrial, mixed-use, special public interest, BeltLine, historic, neighborhood commercial, and overlay districts. Zoning review commonly checks use, setbacks, height, lot coverage, floor area, parking, accessory structures, signs, and overlay standards. Many Atlanta parcels are also subject to tree protection, historic district, BeltLine, neighborhood, or floodplain requirements that can affect permit approval.
Permit Costs
Atlanta permit fees are generally based on project valuation and permit type, with additional fees possible for plan review, inspections, technology/surcharge fees, trade permits, arborist review, fire review, and reinspection. Small trade permits may be roughly $50-$200. Minor residential permits often run a few hundred dollars, while additions and new homes may range from several hundred to several thousand dollars. Commercial fees vary widely with valuation and review complexity.
Engineering Requirements
Georgia-licensed design professional stamps are typically required for commercial buildings, changes of occupancy, structural alterations, additions involving new structural loads, non-prescriptive foundations, retaining walls, significant decks or elevated structures, fire protection designs, special inspections, and projects in flood hazard areas. One- and two-family dwellings may use IRC prescriptive construction when fully compliant, but engineered drawings are required when spans, loads, lateral systems, soil conditions, or structural details fall outside prescriptive limits.
Local Code Adoption
Atlanta administers the Georgia State Minimum Standard Codes as adopted by the Georgia Department of Community Affairs, including the current Georgia-amended IBC and IRC editions, plus local ordinances for zoning, trees, stormwater, fire, and land development. Applicants should verify the current code cycle and amendments at the time of application.
Typical Projects
Common Atlanta permit projects include single-family renovations, basement finishes, kitchen and bath remodels, decks and porches, accessory dwelling units where allowed, garage conversions, additions, new infill homes, multifamily renovations, restaurant and retail tenant build-outs, office renovations, adaptive reuse, signage, tree-impacting site work, and mixed-use development.
